批量檢查某人是否正在使用HDD或SSD

Question

我正在製作一個程序來提升電腦性能，其中一項功能是碎片整理。但如果這個腳本運行一個SSD它不會對它有好處。因此，任何人都知道如何檢測他們是否使用SSD或HDD，以便我可以編程以在需要時跳過此步驟。我想也許是速度測試，但我不知道這是否可靠。有誰知道我該如何做到這一點。謝謝

Answer 1

這些信息可以從wmic命令中獲得;例如：

C:\> wmic logicaldisk get Description,DeviceID 
Description   DeviceID 
Local Fixed Disk C: 
Local Fixed Disk D: 
CD-ROM Disk   E: 
Removable Disk  G: 

下面使用批處理文件中的此方法，以確定是HDD中的驅動器：

@echo off 

for /F "tokens=1-4" %%a in ('wmic logicaldisk get Description^,DeviceID') do (
    if "%%a %%b %%c" equ "Local Fixed Disk" (
     echo Drive %%d is a HDD 
    ) 
) 

例如：

C:\> test.bat 
Drive C: is a HDD 
Drive D: is a HDD 

EDIT：兩個新的驅動器添加識別方法

似乎以前的方法在所有情況下都不可靠。下面有兩個更精確的新方法：一個肯定的方法，檢查給定的驅動器是否是基於LogicalDisk/DriveType = 3的HDD，否定的方法是檢查給定的驅動器是否是而不是 HDD是基於分區上的IDE盤具有（盤驅動/ InterfaceType = IDE）：

@echo off 

echo Drive type identification using LogicalDisk/DriveType=3: 
for /F "tokens=1-2" %%a in ('wmic LogicalDisk get DeviceID^,DriveType') do (
    if "%%b" equ "3" (
     echo Drive %%a is a HDD 
    ) 
) 

echo/ 
echo Drive type identification using DiskDrive/InterfaceType=IDE: 
set partitions=0 
for /F "tokens=1-2" %%a in ('wmic DiskDrive get InterfaceType^,Partitions') do (
    if "%%a" equ "IDE" set /A partitions+=%%b 
) 
set drives=BCDEFGHIJKLMNOPQRSTUVWXYZ 
call set lastIDEdrive=%%drives:~%partitions%,1%%: 
echo Last IDE interface logical drive (B:=none): %lastIDEdrive% 
for /F %%a in ('wmic LogicalDisk get DeviceID') do (
    if "%%a" gtr "%lastIDEdrive%" (
     echo Drive %%a is NOT a HDD 
    ) 
) 

例如：

C:\> test.bat 
Drive type identification using LogicalDisk/DriveType=3: 
Drive C: is a HDD 
Drive D: is a HDD 

Drive type identification using DiskDrive/InterfaceType=IDE: 
Last IDE interface logical drive (B:=none): F: 
Drive G: is NOT a HDD 

Answer 2

簡答：沒有可靠的方法。

龍答：

問題「Is there any way of detecting if a drive is a SSD」提出了一些啓發，但他們都不似乎是可靠的。

此問題也被問到on Lockergnome，但在我的系統上，我無法通過運行MSInfo32從硬盤告訴我的SSD。

On CNet答案是查找驅動器模型和谷歌它。這可能不是您想要從批處理文件中執行的操作。

這post on the OCZ forum建議找一個0的旋轉。但作爲Flimm commented，它有時躺着。

A Wordpress blog post建議使用隨機讀取傳輸速率，但這也是啓發式的。 RAID系統可能會逃避這種檢測。

- 關於@Aacini的答案

更新，證明這是行不通：

腳本報告：

D:\>test-hdd.bat 
Drive type identification using LogicalDisk/DriveType=3: 
Drive C: is a HDD 
Drive D: is a HDD 
Drive E: is a HDD 
Drive F: is a HDD 

Drive type identification using DiskDrive/InterfaceType=IDE: 
Last IDE interface logical drive (B:=none): F: 
Drive G: is NOT a HDD 

真實情況：

Drive C: is a SSD (logical partition 1 of SSD 1) 
Drive D: is a SSD (logical partition 2 of SSD 1) 
Drive E: is a SSD (only partition of SSD 2) 
Drive F: is a HDD 
Drive G: is NOT a HDD (it's a USB stick)

我寫了下面的JavaScript代碼。我需要知道我是否有SSD驅動器，以及它是否是啓動驅動器。

function main() 
{ 
    var retval= false; 
    // MediaType - 0 Unknown, 3 HDD, 4 SSD 
    // SpindleSpeed - -1 has rotational speed, 0 has no rotational speed (SSD) 
    // DeviceID - 0 boot device 
    var objWMIService = GetObject("winmgmts:\\\\.\\root\\Microsoft\\Windows\\Storage"); 
    var colItems = objWMIService.ExecQuery("select * from MSFT_PhysicalDisk"); 
    var enumItems = new Enumerator(colItems); 
    for (; !enumItems.atEnd(); enumItems.moveNext()) 
    { 
     var objItem = enumItems.item(); 
     if (objItem.MediaType == 4 && objItem.SpindleSpeed == 0) 
     { 
      if (objItem.DeviceID == 0) 
      { 
       retval=true; 
      } 
     } 
    } 
    if (retval) 
    { 
     WScript.Echo("You have SSD Drive and it is your boot drive."); 
    } 
    else 
    { 
     WScript.Echo("You do not have SSD Drive"); 
    } 
    return retval; 
} 

main();
